Specification of Letters Patent.

Patented J une 25, i912.

Application led February 8, 1909. Serial No. 476,786.

To all whom t may concern Be it known that l, ARTHUR BATES, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Shoe- Finishing and other Machines, of which the following description, in connection with the accompanying drawings, is a. specification, like reference characters on the drawings indicating like part-s in the several figures.

This invention relates 'to machines for use in the manufacture of boots and shoes and is herein shown as embodied in a machine for nishing shoes by top ironing.

The machine to which the invention has herein been applied may be in general the same as that shown in prior application Serial No. 438,797, filed June 16, 1908.

The object of this invention is to provide improved means for supplying the finishing material adapted to effect econo-mies in the use o-f said material and to permit different kinds of finishing materials to be conven iently used with the same machine.

An important feature of this invention consists in novel means for feeding the finishing material adapted to start the feeding when the work is put into position to be* treated and to stop the feeding when the work is withdrawn. This feature of the invention also contemplates provision for varying during the progress of the operation the rate at which the material is fed and in accordance with the judgment of the workman. To this end the working tool, which is the top ironing tool in this instance and serves to distribute wax and work it into the marginal port-ion of the shoe bottom rubbed by it, has capacity for another movement in addition to its work rubbing movement. This additional movement may be effected, as herein shown, by the work itself lifted in thedirection of working pres-l sure against the tool and operates to start the delivery of wax from the waX holder. For this purpose the tool has an inclined or conical face engaging or adapted to engage a yielding nozzle of the wax holder and Vpress the nozzle backwardly into the holder to open a passageway through which the wax flows to the engaging surface of the working tool. This engaging surface terminates in a wax retaining surface from which the wa-X flows downwardly through the character of the waX or the like supplied to the tool, say, for instance, to enable wax of varying colors to be used.

Accordingly a further feature of the invention consists in the combination with the arrangement for establishing communication between the source of wax supply and the tool of means to enable any one of a plurality of wax receptacles to be brought into coperative relationship with the tool.

A convenient arrangement is one in which eachwax receptacle is provided with a valve that can be brought into range of the tool so that when work is pressed against the tool the latter will be displaced and will actuate the valve that is in cooperative relationship with it to permit wax to be supplied from the receptacle on to the tool.

A convenient embodimentof the invention will now be described as applied to a machine of the type illustrated in the said prior application but it must be understood that this embodiment is by way of example only and that the construction, the arrangement of parts, and its application could be varied without departing from the spirit of the invention.

These and other features of this invention including certain details of construct-ion and combinations of parts will appear in connection with the following description of the machine and will then be pointed out in the claims.

Figure 1 is a side elevation of a top ironing machine equipped with the present in-Y vention; Fig. 2 is a similar view on a larger scale and partly in section; Fig. 3 shows the waxholders in plan; Fig. 4 is a detail of the tool actuating mechanism.

In the machine provided with this embodiment of the invention there is a rotary and oscillating burnishing iron 2 that receives rotary and reciprocatory movements in the manner and by 'the means set forth in the said prior application from a shaft 4 and intermediate connections to the tool spindle 5. In addition however to its movements of rotation and oscillation the iron is arranged so as to be moved upward by the pressure of the work when the latter is raised against the underside of the tool.

Vlio

Conveniently this upward movement may be obtained by mounting the spindle carrying the tool in bearings in swinging frame V tool.

6 by which the oscillation of the tool is obtained. The spindle with the gear wheel 7 by which the spindle and with it the tool is rotated is arranged to have a small amount of end play.

The tool and spindle may be maintained normally in their lowermost position by gravity or by means of a spring mounted in any suitable and convenient manner.

Adjacent to the burnishing tool 2 is a vertical post 10 that carries two or more reservoirs 12, 13 which may contain wax of different colors. The post is adapted to be turned in bearings in the main frame so as to bring a nozzle, with which each reservoir is provided, ito the path of the burnishing tool in its upward movement. The nozzles l5 of the reservoirs are spring controlled in such a way that when either of the nozzles is placed above the burnishing tool, the upward movementof the latter by the pressureof the work will open the nozzle and permit the wax to flow therethrough on to the tool.

YThe upper surface of the burnishing tool is provided with an inclined or conical surface 14 which acts as a cam to displace the nozzle upon the upward movement of the tool.

The nozzle indicated at 15 in Fig. 2 may conveniently consist of a plunger 16 that is perforated and held outwardly from an extension of the casing of the reservoir 12 by a spring 2O located between the end of the plunger and an abutment in the said extension. The nozzleis prevented from being fo-rced out of the extension by the provision of an enlarged portion or collar 21 at its inner end which collar bears upon a ferrule or sleeve 22 screwed into the extension. The perforation through the nozzle terminates in an opening 23 that, when the nozzle is in its extended or normal position, is closed by contacting with the side of the ferrule. When Jthe nozzle is pushed inwardly in opposition to the spring communication is established between the perforation in the nozzle and the interior of the reservoir whereby the wax will flow therethrough and be delivered to the burnishing The flow of the wax may be varied by increasing the upward movement of the tool 2 within limits. yThe edge of the tool is kept free from accumulations of wax by the wiper 24. Y Y

To maintain the particular reservoir containing the wax it is desired to use in the position in which its nozzle is in the path of the burnishing tool a detent device is provided that acts in combination with the vertical shaft 10 hereinbefore referred to as carrying the reservoirs. This device may comprise a plunger 25 located in a recess in the frame and pressed outwardly by a spring 26 seated between the end of the recess and a collar on the plunger. The end ofthe plunger is provided with a coniw cal part that is adapted to engage with one or another of two recesses 27, or of a greater number of recesses when there are more than two reservoirs, in a collar securedto the vertical shaft and thus secure the reservoirs in the required positions.

The two reservoirs are preferably connected so that one burner under that reservoir in action will without burning or wasting the wax keep the other reservoir warm enough to enable it to be used almost i1nmediately it is moved n situ over the burner and into coperation with the iron the other reservoir then moving out of action and from contact with the flame and cooling suiicientlyto prevent wastage of wax or a relatively small burner may be maintained under the reservoir which is 'not in use, as shown in Fig. l.

The operation of the embodiment of the invention will be understood from the foregoing description but it may be briefly recapitulated as follows The reservoir containing the'wax of the color required for the work is turned with the vertical shaft so as to bring its nozzle in the path of the burnishing tool. When work is pressed against the tool the latter is raised and in lifting its `inclined upper surface bears against the end of the spring-pressed nozzle which is forced inward against the action of the spring. This permits the wax contained in the reservoir to pass to the tool and be used upon the work.Y The wax collects more or less in the wax retaining space 30 on the top of the tool and flows from thencev to the wax applying surface 32 through openings 33. Upon withdrawing the work the burnishing tool resumes its normal position and so allows .the spring in the reservoir extension to close the nozzle and thereby arrest the supply of wax. When the wax contained in the other reserf voir, which may be vof another color is re quired for use the vert-ical shaft is turned to bring that reservoir into operative position and the detent 25Awill hold it thus turned while the work is carried out as above described. The oscillation of the'burnishing iron or tool in .dealing with the work will not disconnect the said tool from the wax supply as the amplitude of the oscillation is insufficient to remove the tool out of contact with the nozzle, the spring alwayskeeping the end of the nozzle in contact with the tool notwithstanding that different parts of the curved surface of the tool are brought into contact with the nozzle during the oscillation. This oscillatory movement has, however, an effect which is beneficial in Ythat it carries the convex nozzle engaging surface of the tool forth and back across the nozzle and thus reciprocates the nozzle slightly but enough to facilitate the flow of the wax through the nozzle.
